The course aims to study the problems of thermodynamic and fluid dynamics related to internal combustion engines.
Students are also provided with the theoretical and practical bases for fluid dynamics analysis of external aerodynamics problems using the OpenFOAM software.
This course integrates knowledge from the basic engineering sciences of thermodynamics, combustion and fluid mechanics into the study of the operation and design of internal combustion engines. An introduction to computational fluid dynamics (CFD) is also provided, analyzing the main elements of a simulation: computational mesh, finite volume discretization and turbulence models. The OpenFOAM software will be used for the study of external aerodynamics problems.
